T0 all 'whom z'z may concern:

Be it known that I, AARON VENGER, a citizen of the United States, and a resident of Bayonne, in the county of Hudson and State of New Jersey, have invented a new and Improved Ventilator, of which the following is a full, clear, and exact description.

This invention has relation to ventilators especially designed for show Windows or the like and contemplates as an object means for preventing the formation of steam or frost, or other obscuring agencies on the window by the admission of the outside air to the interior of the window. 4

As a further object the invention contemplates a ventilator of the character described which also functions as a fastening element for securing the window pane clamping elements in clamping relation.

'As-a Astill further object the invention aimsto' provide an extremely simple fand' inexpensivedevice which is :so'arranged and correlated to the window as to assume an ineonspicuousfposition. J

With the above recited' vand other bjects f in view, theY :invention resides inthe novel construction set forth' intheffollowing specicatien, particularly pointed out inthe appended claims andf illustrated'in the accompanying-drawings,l it being understood that'- l theright is reserved to embodiments' other' than 'thoseactually' illustrated herein to the full extent indicated by the'general meaning of thezterms in'which' the claims are eX- pre'ssed. l

Fig. 2 is a fragmentary horizontal' sectional view therethrough taken approximately on the line 2 2 of Fig. l.

Fig. 3 is a vertical fragmentary sectional view through the corner of a show window illustrating a modified form of combined fastening elementJ and ventilator.

Fig. 4 is a horizontal sectional view taken approximately on the line 4-4 of Fig. 3.

Referring to the drawings bv characters of reference, A and B designate the meeting edges of the glass panels of a show window or case and C and D inner and outer clamping strips or rails between which the glass panels A and B are received. Ordinarily 1922. Serial No. 550,432.

a retaining bolt or rivet is passed through the clamping strips or rails C and D to fasten the structure in place.

Under the present invention, a tubular bolt 10 is employed in lieu of the us'u'al 'solid bolt. or rivet, the same being provided with an outturned flange 11 at its outer end constituting a head. The inner end o'f vthe tubular bolt is exteriorly threaded as at12 to receive the internally threaded sleeve 13 provided witli an annular outwardly disposed flange 14. A substantially semispherical head 15 of hollow construction is fitted over and rotatably mounted on the`flange .14,the same being secured in p lace by an "intliriied annular flange 16. The iangeslllland 1'6 are provided with an annular series of perforations 17 which upon rotation ofthe'head 15,

4are ladapted to be broughtinto onojuft bf alignment. When the' sleeve '13 is threaded @n to the threads 12 4ef tn efhenw fboitfrt,

said-sleeve together with tl'ie flangev '11 con'- stitu'te a fastening means for advancing' 'the clamping strips or rails C "a'l'id 'D tvtad; eachother to prevent relative lseparatin thereof and lock the glass pfa'i'ie'ls and B 1n position. Under this arrangementf'whei the semi-spherical -head is rotated to bring the v openings 17 into registration, it 'will be obvious-that the interior-of"the'vviii'd'vi vis' vented to the odtsidev atmosphere; thereby' permitting a circulation-of a'ii thug'ht-lie' tubular bolt 10 into the 'head 15 and tliei-efrom through the aligned opeii'iligs17'- 'asindicated by the arrows. It is, -of c'r's'e, obvious that a pluralityl of fbolt's 1U-with their correlatedparts are?V dis'trbted "vfrtically throughout the length of the wiiid'cfivff' whereby' the uppermost-bolts 1U will'perriit the heated.' air within 'tlie windovi 't6 esape' tlieretlrr--ough vfor setting ya 'constant eifculation. vWhen it is undesirable to admit of the venting of the interior, the semispherical heads 15 are rotated to dispose the openings 17 and the flanges 14 and 16 out of alignment or registration. Rain, snow, or sleet entering the tubular bolt 10 is prevented from passing into the spherical head by an upturned lip 18 at the lower inner extremity of the interior periphery of the bolt.

In the modified adaptation of the invention illustrated in Figs. 3 and 4, the glass panels A and B are provided with mitered meeting edges with which inner and outer angular clamping brackets E and F coact. The apex of the clamping brackets E and F and the. lneetingdges f4 the. glass Panels are prQvided? with registeredj, openings througli"which the tubular-'bolt l0a extends, the same being provided at its outer end with an outturned iiange'llacoifstituting a' head and exteriorly threaded at its inner end as at l22l to receive the interiorly threaded stem 13a of a T-shaped ,union-1421. which stem is threaded against and coacts with the inner bracket; E t0: clamp and fasten the structurein position. vThe head l5a of the T-shaped union is internally threaded to receivethe threaded lower and upper extremitiespoi' the upstanding and depending perforated.tubes,l6 -and 17a; The tube 16a is clpsedjat its upper endand the tube 17a at itlsglovver end. The yinner extremity/of the .l tubularl boltlj()a is provided with aninternalclip 1 8l adjacent the lower= portion thereolitdprevent the passage of rain, sleet or snow therefrom-intothe union 14".
